Specification of Letters Patent.

Patented Nov. 2, 1915.

i Application filedJanuary 30, 1913. Serial No. 745,058.

To aZZ whom it may concern.

Be it known that We, SANFORD L. CLUETT and OI-mamas H. BLACKERT, citizens of the United States, residing at Hoosick Falls, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Harvesters, of which the following is a. specification.

The invention relates to such improvements and consists in the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figures therein. 1

Figure l of the drawings is atopplan view of a harvester having a tongue-truck embodying our invention. Fig. 2 is a similar view on a larger scale of the truck-portion of the harvester. Fig. 3 is a view in side elevation of the truck-portion of the harvester. Fig. 4c is a view in rear elevation, showing one of the truck-wheels, and illustrating the manner in which the same is mounted upon the axle-member by means of a rock-shaft ,7

The principal objects of the invention are to adapt the harvester for making a short turn in either-direction upon its draft-wheel as a pivot; and to counteract or overcome side-draft.

Referring to the drawings wherein the invention is shown in. preferred form, 1 is the body of the harvester, having the draftwheel, 2, cutter-bar, 3, grain-wheel, 4, and stub-tongue, 5, the several parts named bein g of the usual construction.

Upon the forward end of the stub-tongue is fixed a bracket, 6, supporting in fixed relation to the stub-tongue an axle-member, 7 which extends at right angles to the stubtongue and is also connected therewith by means of a diagonal brace, 8. The axlemember, 7, has at each end a bearing, 9, for a vertically arranged rock-shaft, 10, which has fixed upon its lower end a horizontal. axle, 11, for one of the truck-wheels, 12, said rock-shaft terminating at its upper end in a crank Or rocker-arm, 18. The truck-tongue, 14:, has its rear end pivotally connected with the bracket, 6, by means of a bolt or pin, 27. As a preferred means for thus connecting the truck-tongue with the stub-tongue and bracket, we have shown a pivot-block, 15, mounted upon the rear end of the truck-tongue by means of a pair of side-plates or straps, 16, between the forward ends of which the rear end of the truck-tongue is embraced and bolted, and between the rear ends of which the pivotblock is embraced and bolted or riveted, whereby the pivot-block is rigidly fixed to, and becomes substantially part of, the trucktongue.

The bracket, 6, is provided with an aperature extending vertically therethrough adapted to receive the bolt, 27, which bolt also passes through a strap, 17, mounted upon the top of the stub-tongue, between which strap and the bracket, 6, the pivotblock, 15, of the truck-tongue is mounted.

The pivot-block, 15, is provided with a plurality of holes, 18, extending vertically therethrough arranged transversely Of the axis of the truck-tongue, each of which holes is adapted to receive the bolt or pin, 27. By changing the pin, 27, from one to another of the holes, 18, the draft-line of the trucktongue relatively to thestub-tongue can be changed to overcome or counteract sidedraft. 7

The ends of the crank-arms, :13, are connected respectively by links, 19, with the truck-tongue, the rear ends of said links being pivotally connected with the respective crank-arms, and their front ends pivotally connected with the respective lugs, 20, formed upon a box, 21, which is riveted upon the truck-tongue inclosing its strapdnclosed end.

The construction and arrangement of the parts is such that a sidewise swinging move ment of the truck-tongue upon the pivotal connection, 27, is transmitted through the links, 19, and crank-arms, 13, to the axles of the wheels, 12, thereby changing the angular relation of the wheels, 12, to the truck-tongue and giving to the harvester a short turn in the direction in which the truck-tongue is swung.

We have shown fixedly mounted On top of the axle-member, 7, abutment-plates, 22, each having an abutment, 23, in the path of the neighboring crank-arm, 13, adapted to engage and form a positive stop in one direc iarm adapted to engage and form a positive stop for said arm in the opposite direction, with the axle of the neighboring wheel, 12,

k in line with the center of the draft-wheel, 2.

' In either extreme position which the trucktongue ispermitted to assume, the truckwheels will be tangential to a circle, the center of which coincides with the center ofthe draftwheel',f2; so that the driver by merely guiding his team assharply to the left or right as the abutments, 23. and 24k, permit,

can turn the harvester in the smallest posf siblespace, the harvester turning about an axis'pa'ssing through the center of the draftwheel without movement of translation of the draft-wheel.

"'Wehave indicated by dotted lines in Fig. 1 the normal position of the wheels 12;

i v andlin saidfigurehave shown by solid lines the positions assumed by the Wheels, 12, in

one extreme position of the truck-tongue, the angular relation ofthe axes of the wheels,

12, to the draft-wheel being indicated by the I broken linesf25.

We haveascertained that by locating the pivotal connection, 27, of the draft-tongue with'the stub-tongue in rear of a line extending'through the axes of the vertical shafts, 1O, andthe employment of positive stops as described, we are able to attain the result above set forth of turning the harvester in either direction about an axis passing through the center of the draft-wheel.

' What we claim as new and desire to secure 7 by Letters Patent is 1; "In a harvester the combination with the body of the harvester; a main draft- Copies of this patent ma be obtained for wheel; and a stub-tongue; of a truck-tongue pivotally connected with the stub-tongue; an axle-member fixed upon the stub-tongue; a vertical rock-shaft mounted upon each end of said axle-member; an axle projecting horizontally from each rock-shaft; a truckwheel mounted upon each of said axles; connections between the respective rockshafts and the truck-tongue whereby angular movement is imparted to said wheels by sidewise movement of the truck-tongue; and positive stops for determining the angular movement of the respective truck-wheels in each direction with their respective axes in line with the center of the draft-wheel.

2. In a harvester the combination with the body of the harvester; a main draft-wheel; and a stub-tongue; of an axle-member fixed upon the stub-tongue; a vertical rock-shaft mounted upon each end of said axle-member; an axle projecting horizontally from each rock-shaft; a truck-wheel mounted upon each of said axles; a truck-tongue pivotally connected with the stub-tongue on a vertical axis located in rear of a line passing through said rock-shafts; connections between the respective rock-shai'ts and the truck-tongue whereby angular movement is imparted by the truck-tongue; and positive stops for determining the angular movement of the respective truck-wheels in each direction with their respective axes in line with the center of the draft-wheel.

' V In testimony whereof, we have hereunto set our hands this 26th day of December,

J. R. MANHALL.
